outside of Japan (East India, Gulf of Mexico, Alaska, etc.), and 

 19 within Japan, the majority were submarine, only two of the 

 Japan earthquakes having been inland ones. From the observa- 

 tion of these large earthquakes, the average transit velocities of 

 the different phases obtained are as follows : Vj = 13*2 km. per 

 sec, V 2 =6-8, V 3 =:4-5, V 5 =3-3, V 6 =2-8, V T =2-4, V 8 =2-l. 



2. Ready Reference Tables, Volume I. Conversion factors of 

 every unit or measure in use, including those of length, surface,

 arranged for engineers, physicists, students, merchants, etc.; 

 by Carl Hering, M.E. ]6mo, pp. xviii + 196. New York, 

 1904 (John Wiley & Sons). — The great value to the practical 

 worker of a volume of tables, such as the present, is so obvi-

 and typography here are excellent, while the condensed list on 

 the opening pages and the index add much to convenience of use.
